Abstract: The present invention relates to an electrolyte composition for a lead storage battery, which can maintain the performance of a storage battery at low temperature by enhancing the performance and life of a storage battery. It can also be fully charged in a short period of time due to a greater current efficiency. The present invention can extend the life of a storage battery due to its effect of removing white-colored lead sulfate without corrosion at the electrode plates, and may lead to recycling of waste storage batteries ruined by white-colored lead sulfate.
